    But in this context, a 250R owner wont be riding it "normally", would he?

    My GSX150 OEM chain and sprocket are rated for 15k kms with rough usage. My colleague at 25k kms still has perfectly fine C&S

    Thanks about the Cush rubber dampers replacement info. Dint know about that
    I agree that most CBR users won't ride the 250 normally. Especially me 😝. I like to use the full potential of the CBR 250R. And my bike currently at 12.5K kms on the odo just was asked for a chain and sprocket replacement due to regular use of the full potential. Intact even my brake pads don't last long more than 6k kms.
    But then it all comes down to how a person rides their machine.

      [MENTION=86109]MotoBlizzard[/MENTION] - you seem quite firm about certain topics like FS oil and how long a chain should last.

      What life would you expect out of a CBR 250 chain which has done 136 kmph before first service, ridden to 7000 rpm (max torque range) almost every day it's taken out, ridden hard on Ghats on second gear, touched 150-155 more than 10 times?

      25,000? That's what I thought when j bought the bike. Nope. 35,000? That's when I bought a spare chain and sprocket set because I thought death was imminent. Nope. My chain is 45,000 kms done, and the condition is better than hypheni's bike. I've used engine oil, gear oil, and now 2t oil made in 1993 to lube.

      What I've learned is, nothing is entirely black or white. They're just different shades of grey. Some dudes have chains going bust at 16k, some at 20k and some at 35k.

      Afaik, there is one Duke owner on xbhp who has done 45k on his 200's stock chain

        Good for you, must be one hell of a chain.

          It must be in hell maintained condition. Can we see a pic of it please? And yes it was bad of mine that after the purchase I didn't care about the chain for 2 years, as I was very new to biking and never cared about such things except body cleanup.

            My stock chain lasted around 25kish, I didn't maintain it the first 10 k km cause I was a noob 😑, I think it could have done? 35k plus but I cut a couple links a 1000 km before and I knew when the gearbox became clunky to chain the chain sprocket.

              all information regarding the wear and tear of the parts and it's replacement are mentioned in the service manuals so that elimates lots of doubt and this unecessary debate.

                precisely, i am at 30k km on the stock chain on my duke, so is another member on his rc200.. and plenty of other folks too. and we don't 'baby' it too much, just common sense.
                one of the reasons for quicker wear (apart from negligent maintenance) is a chain that has too little slack, and i've observed a lot of mechs adjust it with too little slack.
                some others are just taken for a ride by the svc (due to their lack of understanding/knowledge on how to guage wear & tear).. the svc these days blindly tell you to change the chain/sprocket kit at 12k ~15k km

                • Re: Honda CBR 250R

                  Yes. I have to agree on this part. Mechanic adjust too tight with no load. This causes accelerated wear in the chain. Best way to adjust chain is to adjust the slack when loaded (rider and pillion). Give a 1 cm slack , your bike gear box and chain will be happy. If the setting is correct then it never needs adjustment atleast 10k kms. Dont use any junk can sprays, i am happy with engine oil for every 500~800kms. I have a R15S and its currently 42K kms with original DID chain.

                    As the discussion of chain and sprocket is going on, I would like to ask one more question. I have already shown the condition of my CBR's chain and the ODO is at 25640. From last few days, I am experiencing jerky engine and gear shifts. I can understand that gear shifting is directly related to chain condition but does the chain condition affects the engine smoothness too? Just to mentioned I have just changed the engine oil 500kms back.

                      [MENTION=16602]s1d[/MENTION] - yeah, the SVC is regularly making use of Ave2592's wallets full potential. He doesn't even check the brake pads when the mechanic asks him to replace. And I bet he didn't check the chain wear indicator either, otherwise he would have asked about it here.
                      [MENTION=90280]Ave2592[/MENTION] - no hard feelings bro, it's just that the SVC is there to make money; usually, most people don't check the service bills, or have any knowledge about vehicles.Thus the SVC takes them for a ride, adding in unnecessary things, and avoiding actual work needed. If you are new to vehicles, do read up on the net, there's lots to learn for everyone.

                      [MENTION=57101]hypheni[/MENTION] - I have vibrations on the footpegs, the power comes in with a jerk at any rpm, even with least throttle input, and when lugging, the jerks increase. Sometimes even though the chain may be fine, the sprockets may be worn out or damaged.

                      Below is the condition of my chain after a traffic stop GP with 2 bullets at 45 kmph in first gear.

                        Couldn't understand these hard words. Probably I mislead a bit earlier. The engine is not jerky rather I feel it's not butter smooth, there is some roughness in the sound, the sound is not sweet.

                        And if I'm not wrong your rear tyre is ContiGo. What's the age of it?

                          It's nothing; traffic stop GP is when two or three bikes pull up to a red light, and launch when it turns green. It's a nice way to exercise the engine, and safe in a large, signal with clear visibility and no intersections or pedestrians after the signal. Today I was at one with two Royal Enfield Bullet 350 with annoying rubber ended silencers.


                          About the smoothness, check the bike's sound over a few days for any variation.



                          This is my third rear Contigo. It's up for replacement in another 2k kms. Done 7000 so far. The rubber is so hard you will ruin your nail trying to make an impression on it. Previous Contigos lasted 20k, 18k.

                          I have no issue getting a knee down on plain, clean roads but there are no plain clean roads here. Either the road shoulder is full of sand, or some m800 guy would have stopped bang in the middle of the lane busy chatting with one of his hundred relatives.

                                Just for clarification purposes, you have done 45000 kms and theres no stretching of your chain and sprocket shark toothing?

                                I am asking this because, saying your chain's condition is better than hypheni's doesnt paint a clear picture.
